Company profile

researched Aug 2026

Freya develops voice AI agents that handle inbound and outbound telephone conversations for enterprises, operating 24/7 and supporting dozens of languages and local dialects. The platform covers the full agent lifecycle — training, fine-tuning, testing and deployment — and offers configurations such as an outbound sales agent that contacts prospects, handles objections and logs interactions, and an inbound welcome agent that answers queries, follows defined scenarios and updates contact records.

Typical deployments described by the company include debt collection and payment reminders, policy, coverage, claims and application status inquiries, campaign information and FAQ handling, appointment scheduling, rescheduling and reminders, lead qualification, renewals, quote intake and claim or loan servicing. Freya connects to existing CRM, telecommunications and IVR systems, as well as ticketing platforms, knowledge bases, policy databases, AMS and payment systems, retrieving live data such as account or policy details, updating records and triggering follow-up workflows. Compliance features cited include ingestion of firm-specific policy manuals, regulatory guidelines and operational procedures, call logging and auditability, end-to-end encryption, role-based access control, audit logging, voice verification and SMS two-factor authentication, with references to KVKK, GDPR and SOC compliance. Deployments are offered in both cloud and on-premise form.

Founding story

Co-founders Tunga Bayrak and Tomáš Nepala were roommates at the University of Pennsylvania and started Freya as their second company together. Bayrak, the CEO, previously worked as an AI research engineer building vision-language models for geometric reasoning and on audio transformers, wrote a paper on quantum machine learning at 16, and was a teaching assistant and AI research team member at Penn before dropping out. Nepala, the COO, studied at Wharton and worked across financial services firms including the insurance broker Gallagher. Both cited their exposure to customer support teams struggling with high call volumes as the motivation for the company.

Business model

B2B software: enterprises deploy Freya's voice AI agents in place of, or alongside, traditional call center staffing, integrating the agents into existing CRM, telephony and back-office systems.

Traction

Reported team size of 14 and Y Combinator Summer 2025 batch participation, followed by a $3.5 million seed round. Customer testimonials on the company site are attributed to a chief executive officer and to a managing director of an embedded BNPL product that uses Freya for outbound reminders and inbound FAQ handling without a call center. The company cites figures of over 50% lower cost than traditional call centers, 99% correct answers and a zero word error rate in comparison tests.

Latest developments

In November 2025 Freya announced a $3.5 million seed round with participation from Y Combinator, Rebel Fund, 212 VC, N1 Tech, BD Partners and angel investors, and was hiring for a DevOps engineer role in Istanbul.

Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

An early-stage entrant in the enterprise voice AI agent market, positioned around financial-services-specific compliance and domain tuning versus generic voice bots; listed alongside other voice AI platforms such as Agora, Sindarin and Leaping AI in a sector directory.

Positioning centers on speech quality described as indistinguishable from a human voice, domain-tuned models trained on industry terminology, policy-aware compliance behavior with auditable call logs, direct integration into existing CRM/telephony/IVR stacks without migration, and support for on-premise as well as cloud deployment.

Technology

Voice AI agents designed for human-like speech, custom-trained on industry terminology and workflows, with the ability to reason over internal policy manuals, regulatory documents and industry guidelines. The stack includes native integrations with CRM, AMS, ticketing, knowledge base, policy and payment systems, real-time record updates and workflow triggers, encryption, role-based access controls and audit logging, voice verification and SMS two-factor authentication, and support for cloud and on-premise deployment at a scale the company describes as thousands of simultaneous calls.

Go-to-market

Direct outreach to enterprise CX, operations, collections and claims leaders, supported by a website demo request, a founders@ contact address and a Y Combinator launch post; the company also highlights quick setup that requires no engineering or system migration.

Enterprises with high call volumes, with a stated focus on banking, financial services and insurance — including banks, mortgage lenders, fintechs and insurers — as well as retail; buyer personas cited are heads of customer experience, operations, collections and claims.

Geography

Headquartered in San Francisco with operations across Europe; described as Czech-founded with founders from Turkey and the Czech Republic. Directory listings note US and Middle East coverage, a job posting is based in Istanbul with remote-in-Turkey option, and the website includes Turkish-language content and references to KVKK alongside GDPR.

History

Founding year is given as 2025 in Y Combinator and directory listings and as 2024 in press coverage. The company took part in Y Combinator's Summer 2025 batch with Jon Xu as primary partner, and announced a $3.5 million seed round in November 2025 that was reported as oversubscribed within two weeks and closed shortly after YC Demo Day.

Risks & controversies

Sources give conflicting founding years (2024 in press coverage versus 2025 in Y Combinator and directory listings). Performance claims such as a zero word error rate, 99% correct answers and 30% better accuracy than generic AI are company-stated and not independently verified in the available material, and customer testimonials are attributed to individuals without naming the client organizations.
